On my Linux desktop I have houndres of GUI apps, no slowdowns, nothing running in the background without knowleadge. It’s just a disk space. Programs/apps can be uninstalled with keeping their data, so on later install it’s still there.
And can we stop making separate apps for loyality cards or taxi networks, please? We need to keep programs universal. I don’t want an app for [insert company] [insert name of their “smart” home product], I want protocols and standards.
